• Storage: Store at -20°C or below.For economy of use it is recommended that the reconstituted solution be subdivided into several small containers, which are frozen rapidly to below -40°C and then stored below -40°C in the dark. Repeated freezing and thawing should be avoided.
• contents: Each ampoule contains the residue after freeze drying of 1.0ml of a solution that contained: 25 mg of a powder prepared from acetoneextracted posterior lobe of porcine pituitary gland.
